This summer I will be traveling around the U.S. collecting photos and observations for the book, but obviously I won't be able to do it all myself. Below is a list of some high priorities; I will revise and refine it periodically. Feel free to make suggestions of other things to include, if you think I'm missing something. If you are interested in contributing photos or helping in any other way, please email me at ceiseman(AT)gmail(DOT)com. All photos that are not mine will be credited in the photos' captions. Note that I need to have all the photos together by early 2009.
Tracks of horseshoe crab, sand crab, and assorted desert arachnids
Distinctive wood borings of known species/families
Leaves rolled by leaf-rolling cricket and leaf-rolling weevil
Mud nests of known wasps and bees (other than Trypoxylon politum and Sceliphron caementarium)
Any spider webs that are representative of a family or unique to a species/genus--these are hard to get good photos of,
even if they are easy to find
Distinctive egg sacs and egg cases of known spider and insect taxa. Priorities include Argiope spp., hydrophilids, dobsonfly,
and the mud cells made by certain carabids (Brachinus, Galeritula, Chlaenius, Pterostichus, Craspedonotus, Carabus, Calosoma)
Eggs of chrysopids, reduviids, pentatomids, coreids, and any distinctive aquatic eggs
Caddisfly cases representative of families (Helicopsychidae and Glossosomatidae would be especially nice)
Whirligig pupal chamber
Trapdoor spider burrows; examples of wafer, cork, and folding doors would be ideal
Purseweb spider tubes
Signs of Strepsiptera and dryinids
Cicada egglaying scars; Monochamus egg niche
Bark stripping by European hornet
Mass of Atherix corpses and eggs
Distinctive galls and leaf mines of known taxa
